NPE in Tomcat parseParameters()
-------------------------------

                 Key: JBSEAM-1974
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1974
             Project: JBoss Seam
          Issue Type: Bug
          Components: Wiki
            Reporter: Christian Bauer
         Assigned To: Christian Bauer
            Priority: Minor


This is still a mystery, only occurs from time to time on the production site. Google says that this might be related to the 64 bit VM, others say that the lifecycle of the request object usage is wrong. The crazy part is that the Authenticator component doesn't even have any @RequestParameter anymore, so no idea why Seam wants to inject it.

Caused by: java.lang.NullPointerException
